IPO Filed Jun 1, 2026
Confidential S-1 filed, October 2026 listing target
Valuation: $965B

Anthropic confirmed Monday June 1, 2026 it had confidentially filed a Form S-1 with the SEC, four trading days after the $65B Series H at $965B post-money. Filing is confidential, no public revenue or risk disclosure yet. Run-rate cited at roughly $47B (May 2026) vs $10B a year prior. Targets an October 2026 listing. Wilson Sonsini (Google's 2004 IPO counsel) retained. Filing beat OpenAI's expected confidential filing 'within weeks' to the punch.
